【摘要】:大慶長(zhǎng)垣扶余油層近幾十年的勘探開(kāi)發(fā)所動(dòng)用的儲(chǔ)層主要是中高滲油層,但隨著勘探開(kāi)發(fā)的深入發(fā)展,低滲透原油產(chǎn)量每年都在遞增,低滲透儲(chǔ)層已成為油氣增儲(chǔ)增產(chǎn)的新主力戰(zhàn)場(chǎng)。因此,系統(tǒng)研究低滲透儲(chǔ)層特征及深入剖析其優(yōu)質(zhì)儲(chǔ)層成巖主控因素成為當(dāng)前促進(jìn)低滲透油層勘探開(kāi)發(fā)的最急需最基礎(chǔ)的工作任務(wù)。本論文針對(duì)大慶長(zhǎng)垣扶余油層儲(chǔ)層以低滲透為主,儲(chǔ)層物性縱橫向變化大、相對(duì)優(yōu)質(zhì)儲(chǔ)層預(yù)測(cè)難的特點(diǎn),綜合運(yùn)用石油地質(zhì)學(xué)、光性礦物學(xué)、沉積巖石學(xué)和構(gòu)造地質(zhì)學(xué)等相關(guān)專業(yè)知識(shí),結(jié)合儲(chǔ)層研究技術(shù)方法,如偏光顯微鏡、掃面電鏡、X-射線衍射儀以及圖像分析軟件系統(tǒng)等,開(kāi)展低滲透含油區(qū)儲(chǔ)層特征的綜合研究。完成了研究區(qū)扶余油層巖石學(xué)特征及物性特征,儲(chǔ)集空間類(lèi)型及結(jié)構(gòu),儲(chǔ)層成巖作用及儲(chǔ)層控制因素的研究分析。研究結(jié)果表明:扶余油層中常規(guī)儲(chǔ)層以低泥/鈣含量的砂巖為主,致密儲(chǔ)層中高泥/鈣含量的砂巖比例增多;其中礦物組成對(duì)儲(chǔ)層類(lèi)型影響明顯,石英和長(zhǎng)石是形成儲(chǔ)層的有利物質(zhì)基礎(chǔ);扶余油層常規(guī)儲(chǔ)層粒度組成主要為中細(xì)砂巖,而致密儲(chǔ)層主要為粉砂巖,泥質(zhì)含量較高,砂巖粒度對(duì)致密儲(chǔ)層影響作用較弱,其粒度與物性相關(guān)性較差;在孔隙結(jié)構(gòu)上,扶余油層常規(guī)儲(chǔ)層喉道較粗,平均喉道半徑在100nm~1000nm之間,而致密儲(chǔ)層喉道較細(xì),以50nm~500nm為主;機(jī)械壓實(shí)作用、膠結(jié)作用以及溶蝕作用是對(duì)儲(chǔ)層具有重要影響的成巖作用,其中機(jī)械壓實(shí)作用對(duì)儲(chǔ)層的破壞性最大,膠結(jié)作用破壞性主要在局部起主導(dǎo)作用,溶蝕作用是改善儲(chǔ)層結(jié)構(gòu),形成儲(chǔ)層的有利因素。
[Abstract]:The reservoirs used in the exploration and development of Fuyu reservoir in Daqing Placanticline in recent decades are mainly medium-high permeability reservoirs, but with the further development of exploration and development, the production of low-permeability crude oil is increasing every year. Low permeability reservoir has become a new main battlefield of increasing oil and gas reservoir and increasing production. Therefore, it is the most urgent and basic task to study the characteristics of low permeability reservoir and analyze the main diagenetic factors of its high quality reservoir in order to promote the exploration and development of low permeability reservoir. This paper aims at the characteristics of Fuyu reservoir in Daqing Placanticline, which is characterized by low permeability, large variation of reservoir physical properties in longitudinal and horizontal directions, and difficulty in predicting relatively high quality reservoirs. The comprehensive use of petroleum geology and photometric mineralogy is used in this paper. Combined with the technical methods of reservoir research, such as polarizing microscope, scanning electron microscope (SEM), X-ray diffraction (SEM) and image analysis software system, the comprehensive study of reservoir characteristics in low permeability oil-bearing areas is carried out. The petrological and physical characteristics of Fuyu reservoir, the type and structure of reservoir space, the diagenesis of reservoir and the controlling factors of reservoir have been studied and analyzed. The results show that the conventional reservoir in Fuyu reservoir is dominated by sandstone with low mud / calcium content, and the proportion of sandstone with high mud / calcium content in dense reservoir increases. Quartz and feldspar are the favorable material foundation for reservoir formation, the grain size composition of the conventional reservoir in Fuyu reservoir is mainly medium fine sandstone, while the dense reservoir is mainly siltstone, the content of clay is high, the influence of sandstone granularity on tight reservoir is weak, In pore structure, the throat of Fuyu reservoir is coarse, the average throat radius is between 100nm~1000nm, and the throat of dense reservoir is fine, mainly 50nm~500nm. Cementation and dissolution are diagenesis which has important influence on reservoir. Mechanical compaction has the most destructive effect on reservoir, the destruction of cementation is mainly in local area, and dissolution is to improve reservoir structure. A favorable factor in the formation of a reservoir.
